Monohybrids and the Punnett Square Guinea Pigs

The video explores the genetics of hair in guinea pigs, focusing on the difference between dominant and recessive alleles. It explains how genotypes and phenotypes are determined, using hairless guinea pigs as an example. The video also covers the concept of monohybrid crosses and how to use Punnett squares to predict genetic outcomes. It emphasizes that these predictions are probabilities, not certainties, and concludes with a reminder of the excitement in studying biology.
